The intrinsic high tissue contrast medium for MRI is one of major strengths of this modality. Whereas CT uses differences in x-ray attenuation coefficients of two adjacent tissues, MR signal is intrinsic and is generated by changing proton spins in response to external RF pulse.

Brain and cervical spinal MRI should be done as soon as possible because of its sensitivity and specificity regarding pattern of injury and timing parameters [23,124,128,203-216]. Brain MRI should include T1, T2, T2*, FLAIR, and diffusion imaging (DWI / ADC). Gadolinium-enhanced T1 images should probably be used along with MRA and MRV.

MRI [Magnetic Resonance Imaging]—see Chapter 2. NEX [Number of EXcitations] If it takes n RF shots and readouts to get the data needed for one image, one might want to acquire more data than are strictly necessary. These redundant data can be used for signal averaging, which will reduce the effects of noise on the final product.

– MRI shows extensive brain infiltration when CT fails to produce any image abnormality. most protocols include T1, proton density, and T2 images. Many brain tumors will not be seen unless contrast medium is used (small lesions that lack mass effect and edema may only be detectable on contrast-enhanced MRI)

MRI/MRA. MRI: clear advantages of MRI of the brain over CT scanning of the head include better imaging of tissues, superior imaging within the posterior fossa, additional places of imaging, and no exposure to radiation. MRA: clear disadvantage of brain MRI is it may or may not identify hemorrhage.
